CFD Simulation of a real engine compressor including consideration of the deformation during operation

Failure analysis and optimization of an aero engine combustion chamber

In order to identify the root cause for severe damages in the combustion chamber, a comprehensive simulation using Ansys CFX has been carried out. The simulation contains all piece parts of the real hardware and shows that the original design of the chamber and the staging of the combustion leads to areas with undesired hot spots. Additionally, a weakness of the cooling concept generates unprotected areas, which are the starting point for oxidation and burnings. The development of a design alteration has also been supported by numerical simulation.
